This machine produces bands going through the image on full color copies/prints, I don't see it on copies with 10% color coverage. So far I've changed the transfer belt, transfer roller and fuser. Removed and cleaned the LSU assy and replaced the MFP pcb and installed new firmware with no luck. The image shows up on the paper at the transfer belt. I have not replaced the IU's because the lines are consistent through each color, any help will be greatly appreciated.

I have seen IUs cause problems for the preceding colors, since black is furthest to the right it can cause issues for the other three.
